Your question doesn't have enough details in order to provide the solution, if you need input from us you need to provide:
1st line of your .jtl file
2nd line of your .jtl file
Line 98797899 of your .jtl file
Line 98797900 of your .jtl file (if exists)
According to the error you're getting, the columns number doesn't match the header/current JMeter configuration so I can think of the following options:
Your test result is really incomplete, if this is the case - either re-run your test and wait for graceful shutdown of all threads or delete the last line of your .jtl file using your favourite text editor. If your test ends prematurely due to error which you don't expect - make sure to check jmeter.log for the execution and follow recommendations from 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure
If you're merging 2 different .jtl result files make sure that JMeter Results File Configuration is the same for both, if there is an extra column in one of them which you can omit - delete this column and amend the configuration
As the last resort you can try generating tables and charts using JMeterPluginsCMD Command Line Tool which is more "tolerant" to the results file configuration and tries to "guess" the format from the file itself
